Description

Technisches GebietTechnical area

Die vorliegende Offenbarung betrifft ein System und dazugehörige Elemente zur Aufhängung oder Befestigung von Gegenständen. Insbesondere betrifft sie Systeme und Elemente zur Aufhängung von Beleuchtungseinrichtungen an Decken oder Wänden.The present disclosure relates to a system and associated elements for suspending or securing articles. In particular, it relates to systems and elements for suspending lighting fixtures on ceilings or walls.

Hintergrund der ErfindungBackground of the invention

Es ist eine Vielzahl von Systemen zur dauerhaften Befestigung von Gegenständen an Gebäudedecken oder Wänden bekannt. Bekannt sind z.B. Haken bzw. Ösen, die an dem Gegenstand angebracht sind und mit dem jeweiligen Gegenstück eingreifen, das etwa an einer Raumdecke befestigt ist. Soll eine stabile dauerhafte Befestigung erzielt werden, ist oft der Haken oder die Öse am aufzuhängenden Gegenstand fest angebracht, was eine genaue Positionierung des Gegenstücks an der Wand erfordert, also dessen genaue Montage. Bekannte Systeme schränken meist die Variabilität der Aufhängung ein, das heißt, beim Austausch des Gegenstands, etwa einer länglichen Leuchte wie einer Leuchtstoffröhre, gegen einen längeren desselben Typs müssen die Befestigungselemente an der Decke weitgehend neu angebracht werden. Dies ist etwa bei der Beleuchtung von Industriehallen unvorteilhaft, da gegebenenfalls ein hoher Arbeitsaufwand und damit Kosten erzeugt werden. Standesgemäße Aufhängesysteme sind bekannt aus DE 20 2006 003262 U1 und US 4 230 297 A .There are a variety of systems for permanent attachment of objects to building ceilings or walls known. For example, hooks or eyelets are known, which are attached to the object and engage with the respective counterpart, which is attached approximately to a ceiling. If a stable permanent attachment can be achieved, often the hook or eye on the object to be suspended firmly attached, which requires an accurate positioning of the counterpart on the wall, so its accurate installation. Known systems usually limit the variability of the suspension, that is, when replacing the object, such as an elongated lamp such as a fluorescent tube, against a longer of the same type, the fasteners must be largely re-attached to the ceiling. This is unfavorable, for example, in the lighting of industrial halls, since possibly a high workload and thus costs are generated. Appropriate suspension systems are known from DE 20 2006 003262 U1 and US 4 230 297 A ,

Vor diesem Hintergrund besteht ein Bedarf nach der vorliegenden Erfindung.Against this background, there is a need for the present invention.

Detaillierte BeschreibungDetailed description

Auch wenn bevorzugte Ausführungsformen beschrieben werden, ist der Schutzbereich der Erfindung nicht auf dargestellten Ausführungsformen beschränkt, sondern umfasst auch für den Fachmann naheliegende Ausführungsformen.Although preferred embodiments are described, the scope of the invention is not limited to the illustrated embodiments, but also includes embodiments obvious to those skilled in the art.

Fig. 1 zeigt ein Aufhängesystem 10 gemäß Ausführungsformen der Erfindung. Es umfasst zwei, im Wesentlichen identische, Winkelelemente 5. Diese umfassen jeweils ein rechtwinklig gebogenes Blech 7, das eine Biegekante 8 aufweist. Diese unterteilt die Winkelelemente 5 jeweils in zwei Segmente 12, 13, die im rechten Winkel zueinander stehen. Dabei ist jeweils ein Segment 12 des Winkelelements 5 mit einem Loch 15 versehen. Die Biegekante 8 ist auf einem Teil ihrer Länge mit einem sich von einem Ende der Biegekante aus erstreckenden Schlitz 17 versehen. Fig. 1 shows a suspension system 10 according to embodiments of the invention. It comprises two, substantially identical, angular elements 5. These each comprise a rectangularly bent plate 7, which has a bending edge 8. This subdivides the angle elements 5 into two segments 12, 13, which are at right angles to each other. In each case, a segment 12 of the angle element 5 is provided with a hole 15. The bending edge 8 is provided on a part of its length with a slot 17 extending from one end of the bending edge.

Die beiden Winkelelemente 5 lassen sich mittels der Schlitze 17 so um 180 Grad gegeneinander verdreht so ineinander schieben lassen (siehe Fig. 1), dass die beiden Löcher 15 zur Deckung kommen und zusammen eine durchgehende Öffnung ergeben (siehe etwa Fig. 5). Die jeweils anderen, lochlosen Segmente 13 der Winkelelemente 5 ergeben dann zusammen eine Grundfläche. Diese kann mit ihren zwei gegenüberliegenden Kanten 18 in gegenstückig ausgeführte Aufnahmen, die vorzugsweise als Nuten ausgelegt sind, in eine aufzuhängende Vorrichtung eingreifen, wie etwa eine Deckenleuchte. Da die beiden Segmente 12 mit den Löchern dicht aneinanderliegen und die Bewegung der Winkelelemente 5 voneinander weg im montierten Zustand durch die Nuten 55 blockiert ist, ergibt sich eine stabiler Kraftschluss von den Nuten bis zu einem z.B. Wand-Haken, der durch die durchgehende Öffnung geführt ist.The two angle elements 5 can be so by 180 degrees against each other twisted by means of the slots 17 can be pushed into each other (see Fig. 1 ) that the two holes 15 come to coincide and together give a through opening (see Fig. 5 ). The respective other, holeless segments 13 of the angle elements 5 then together form a base. This can engage with its two opposite edges 18 in oppositely executed receptacles, which are preferably designed as grooves in a device to be suspended, such as a ceiling light. Since the two segments 12 are close to each other with the holes and the movement of the angle elements 5 is blocked away from each other in the assembled state by the grooves 55, a stable adhesion results from the grooves to a wall hook, for example, which passed through the through hole is.

Fig. 2 zeigt eines der oben beschriebenen Winkelelemente 5 für ein Aufhängesystem 10. Es umfasst das rechtwinklig entlang der Biegekante 8 gebogene Blech 7, die das Blech in zwei Segmente 12, 13 unterteilt. Das Blech 7 weist im Bereich der Biegekante 8 einen von ihrem Ende entlang der Biegekante verlaufenden Schlitz 17 auf. Eines der Segmente 12 ist mit einem Loch 15 versehen. Dieses wirkt mit dem Loch des anderen Winkelelements zusammen, wie bei Fig. 1 beschrieben und in Fig. 5 dargestellt. In einer Abwicklung auf eine ebene Fläche weist das Winkelelement 5 im Wesentlichen zwei zusammengesetzte Grundformen auf, ein Rechteck bzw. Quadrat sowie ein daran angesetztes Dreieck. Das Loch 15 ist dabei im Bereich des Dreiecks vorgesehen. Der Schlitz 17 verläuft typischerweise mindestens über die Hälfte der Länge der Biegekante 8 oder darüber hinaus. Fig. 2 shows one of the above-described angle elements 5 for a suspension system 10. It comprises the perpendicular bent along the bending edge 8 sheet 7, which divides the sheet into two segments 12, 13. The sheet 7 has, in the region of the bending edge 8, a slot 17 extending from its end along the bending edge. One of the segments 12 is with a Hole 15 provided. This interacts with the hole of the other angle element, as in Fig. 1 described and in Fig. 5 shown. In a development on a flat surface, the angle element 5 has essentially two composite basic shapes, a rectangle or square and a triangle attached thereto. The hole 15 is provided in the region of the triangle. The slot 17 typically extends at least over half the length of the bending edge 8 or beyond.

Fig. 3 zeigt eine andere Ansicht des Winkelelements 5 der Fig. 2, wobei in der Draufsicht der Verlauf des Schlitzes 17 sichtbar ist. Fig. 3 shows another view of the angle element 5 of Fig. 2 , wherein in the plan view of the course of the slot 17 is visible.

Fig. 4 zeigt eine perspektivische Darstellung des Aufhängesystems 10 der Fig. 1, gemäß Ausführungsformen. Die beiden Winkelelemente 5 können von der dargestellten Position aus zusammengeschoben werden. Der dadurch erreichte Endzustand des Aufhängesystems 10 ist in Fig. 5 dargestellt, wobei erkennbar ist, dass die beiden Löcher der Winkelelemente 5 die durchgehende Öffnung ergeben. Fig. 4 shows a perspective view of the suspension system 10 of Fig. 1 , according to embodiments. The two angle elements 5 can be pushed together from the position shown. The final state of the suspension system 10 achieved thereby is in Fig. 5 wherein it can be seen that the two holes of the angle elements 5 give the through opening.

Fig. 6 zeigt ein Beleuchtungselement 50 mit zwei Aufhängesystemen 10 gemäß Ausführungsformen. Das Beleuchtungselement 50 ist im Beispiel eine Deckenleuchte. Sie hat an ihrer Oberseite zwei längliche, parallel verlaufende Nuten 55, deren Öffnungen zueinander gerichtet sind. Die gegenüberliegenden Kanten 18 des Aufhängesystems (vgl. Fig. 1) greifen in die Nuten 55 ein. Ein Befestigungsmittel (nicht gezeigt) dient zur Befestigung an einer Wand. Dies kann etwa ein Haken sein, der mit einem Ende in die durchgehende Öffnung des Aufhängesystems 10 greift und etwa in eine Gebäudedecke eingedübelt ist. Durch Verschieben der beiden Winkelelemente 5 gegeneinander, bzw. in Längsrichtung voneinander weg, lässt sich das Aufhängesystem 10 einfach wieder von dem Beleuchtungselement 50 lösen. Fig. 6 shows a lighting element 50 with two suspension systems 10 according to embodiments. The lighting element 50 is a ceiling light in the example. It has at its top two elongated, parallel grooves 55, whose openings are directed towards each other. The opposite edges 18 of the suspension system (see. Fig. 1 ) engage in the grooves 55. A fastener (not shown) is for attachment to a wall. This may be about a hook, which engages with one end in the through hole of the suspension system 10 and is dented about in a building ceiling. By shifting the two angle elements 5 against each other, or in the longitudinal direction away from each other, the suspension system 10 can be easily solved by the lighting element 50 again.

In Fig. 7 ist eine abgewandelte Ausführungsform auf Basis des Winkelelements der Fig. 2 dargestellt. Der Unterschied zur Fig. 2 besteht darin, dass das Loch 15 als Langloch ausgeführt ist. Dieses verläuft von der Mitte des Elements zur Seite hin und ist zur Seite des - hier exemplarisch - dreieckigen Teils hin geöffnet, und verläuft im Wesentlichen parallel zur Biegekante 8. Wenn zwei dieser Winkelelemente 5, ebenso wie in Fig. 1 oder in Fig. 4 dargestellt, gegenläufig ineinandergeschoben werden, ergibt die Kombination der beiden Langlöcher 15 zusammen wieder eine kreisförmige Öffnung, ebenso wie etwa in Fig. 5 dargestellt. Mit dieser Variante kann die Aufhängung z.B. ohne Bewegung der aufgehängten Last - allerdings unter Anwendung einer diese unterstützenden bzw. die Aufhängung entlastenden Haltekraft - gelöst werden, indem die beiden Winkelelemente 5 auseinander bewegt bzw. voneinander weg bewegt werden. Zudem lässt sich die Aufhängung auch sehr einfach an geschlossenen Decken-Halteelementen anbringen, z.B. an Ösen, oder an einem in Richtung der Normalen der kreisförmigen Öffnung verlaufenden (Stahl-)Seil. Im Vergleich zur Ausführung wie in Fig. 2 ist die maximal zulässige Kraft bei der Variante der Fig. 7 geringer, weil die vom Deckenhaken o.Ä. eingeleitete Kraft, im Vergleich zur etwa in Fig. 2 gezeigten Ausführungsform, nur noch über eine Seite übertragen wird. Demgemäß kann die Materialstärke des Winkelelements ggf. entsprechend angepasst/erhöht werden. Entsprechende Berechnungen zur (dauerhaften) Stabilität der Winkelelemente 5, auch unter wiederholten Lastwechseln, kann der Fachmann ggf. gemäß seinem Fachwissen über numerische Methoden wie FEM durchführen.In Fig. 7 is a modified embodiment based on the angle element of Fig. 2 shown. The difference to Fig. 2 is that the hole 15 is designed as a slot. This extends from the center of the element to the side and is open to the side of - here exemplary - triangular part, and extends substantially parallel to the bending edge 8. If two of these angle elements 5, as well as in Fig. 1 or in Fig. 4 shown, in opposite directions are pushed together, the combination of the two slots 15 together again gives a circular opening, as well as in Fig. 5 shown. With this variant, the suspension, for example, without movement of the suspended load - but using a supporting this or supporting the suspension relieving holding force - be solved by the two angle elements 5 moved apart or moved away from each other. In addition, the suspension can also very easily attach to closed ceiling support elements, for example on eyelets, or on a running in the direction of the normal of the circular opening (steel) rope. Compared to the execution as in Fig. 2 is the maximum permissible force in the variant of Fig. 7 lower because of the ceiling hook o.Ä. initiated force, compared to approximately in Fig. 2 shown embodiment, is transmitted only on one side. Accordingly, the material thickness of the angle element can optionally be adjusted / increased accordingly. Corresponding calculations for the (permanent) stability of the angle elements 5, even under repeated load changes, can be carried out by the person skilled in the art according to his specialist knowledge of numerical methods such as FEM.

In Ausführungsbeispielen wird ein Beleuchtungselement mit Aufhängesystem bzw. die Elemente dafür sowie ein entsprechend ausgestattetes Beleuchtungselement bereitgestellt, die eine hohe Stabilität und Haltekraft mit sehr einfacher Handhabung und hoher Flexibilität verbinden. In embodiments, a lighting element with suspension system or the elements thereof and a correspondingly equipped lighting element are provided which combine high stability and holding power with very simple handling and high flexibility.
